[time-nuts] HP E1938 oscillator

[Rob Kimberley]

I've been involved with importing and exporting electronic goods including
Rb and OCXO from the US for more years than I care to remember. Unless
things have been tightened up radically recently, all that was required on
most of these items is an End User Statement - i.e. a record of where the
goods are going to be finally used.

In the good old days, the guideline used to be anything with a stability of
1E-9 per day or better needed an Export Licence!

If coming from another country, then local rules apply, although any members
of NATO would typically be utilising US rules for restricted items.

As far as I have been able to ascertain the list of export controlled items
is virtually identical for most western countries and Russia.
There are some slight variations (mainly additions) between countries.
No doubt (for Russia at least) the country list classifications differ.

I stumbled over the local NZ list of export controlled items, as usual
purely by accident, when searching for something somewhat unrelated
(External cavity diode lasers).

As far as I can tell by perusing the complete CCL list (US version) neither
the E1938A nor any of its component parts is a controlled item.
It would take a creative interpretation by an incompetent lawyer to apply
the section on Atomic frequency standards to the E1938A which is not by any
stretch of the imagination an Atomic frequency standard. It is not capable
of being space qualified without substantial redesign nor is it capable by
design of achieving a drift of 1E-11 or less per month.

Since the US has no jurisdiction here I can give well intentioned advice
without worrying about prosecution (as long as I don't visit the US at
least).
